If you resign accounts every time you feel like it, you will soon have an empty portfolio. However, there are two circumstances in which resignation is the wisest choice:
When the agency would be more profitable without the account. This is a rare occurrence, but it does happen. Sometimes, a client is not worth the trouble, and their demands and expectations outweigh the benefits they bring to the agency.
When the client bullies the business to such an extent that the morale of your staff is seriously impaired, and their performance on other accounts starts to suffer. In such cases, it is better to cut ties with the client than to allow them to harm the agency's culture and the quality of work produced.
Remember, we must always prioritize the well-being of our agency and our staff. If a client's demands or behaviour become detrimental to our organization, we must have the courage to let them go.
